The problem is that the people doing the surveillance are hardly going around honestly telling people what's their surveillance profile.

For example in the UK that "pink knit cat hat white lady" would very likely be under surveillance if she was a member of the Green Party and participated in demonstrations. In fact, recently a number of cases came out where in the 80s and 90s the police had infiltrated Ecologist groups and even left some of the women in those groups pregnant with the children of men they late found out were undercover agents.

Further, the lower the barrier to entry to surveillance the lower the "threat profile" needed to end up under surveillance: if the authorities have already have well established and commonly used processes backed by ultra-broad surveillance court (or whatever those courts are called in your country) orders to just get from the mobile network providers all the phone numbers that connect to specific cell towers during a specific time period (such as the ones nearer a demonstration during that demonstratiom), pink knit cat lady is going to end up in the list just as easilly as baclava-wearing hard-core anarchist looking to break stuff.

They might not hack the pink knit cat hat lady's mobile to install eavesdropping software, but she's still in the list for every demonstration she attended carrying her phone and for the authorities finding out those who were at multiple demonstration and cross-searching with other databases to resolve those numbers to actual identities is pretty easy unless those people jumped through hops to keep those things disconnected (which, funny enough, smart anarchists are more likely to have done than your average pink knit cat hat lady)
